PITTSBURGH — Antwaan Randle El is back with the Pittsburgh Steelers, and that’s a very un-Steelers-like move. Free agents leave all the time in the NFL, and the Steelers are no exception. It’s rare that bring players back, though. Randle El left three years ago for a big-money deal with the Washington Redskins. The Steelers wanted to keep him, but there was no way they were going to pay their No. 3 receiver anywhere near what the Redskins were offering. Now he’s back as the No. 3 receiver, and it seems like a win-win situation. The Steelers get a reliable playmaker at a manageable price. Randle El is in a comfortable situation and has banked all of his Redskins money. Mike Wallace had a good season as a rookie, but Randle El can do a lot of things. If offensive coordinator Bruce Arians wants to incorporate some trick plays, Randle El is a weapon. It remains to be seen if Randle El is still as dangerous a kick returner as he was in his first stay with the Steeler.
